(Cl. 16S-15) 9 Claims.

This invention relates to improvements in oil well savers and strippers for oil well pumping equipment.

The primary object of this invention is the provision of a relatively simple type `of oil well stripper and saver which may be used with facil ity to strip and clean oil from sucker rods, or which may be used to close oli the well when the pump line is drawn therefrom.

Other objects and advantages of this invention will be apparent during the course of the following detailed description.

In the accompanying drawings, forming a part oi this specification, and wherein similar reference characters designate the corresponding parts throughout the several views,

Figure 1 is a plan view of the oil well saver and stripper.

Figure 2 is aside elevation of the oil well saver and stripper.

Figure 3 is a longitudinal sectional view taken through the oil well saver and stripper, substantially on the line 3 3 of Figure 1.

Figure 4 is a sectional View taken through the oil well saver and stripper substantially on the line 4-4 of Figure 1.

Figure 5 is a view similar to Figure 4, but with one of the wipers in oil well closing position.

Figure 6 is an enlarged fragmentary sectional view taken through certain details which con-1 trol the longitudinal and rotary movement of one of the sucker rod wipers.

Figure '7 is an end view of a member which supports one of the rod wipers.

Figure 8 is a View of the key slot side of one of the wipers, showing the relation of the key way to the sucker rod oil stripping way of the wiper.

In the drawings, wherein for the purpose of illustration, is shown only a preferred embodiment of the invention, the letter A may generally designate the improved oil saver and stripper, which is adapted to strip oil from sucker rods B; It includes a housing C; wipers D and E; means F for each of the wipers to advance and retract the same with respect to the sucker line, and G indicates means provided for each of the Wipers D and E for rotating the wipers in order to close oi the well after removal of the sucker rod line.

The housing construction C of the improved oil saver and stripper is divided into sections ||l Vand These housing sections l andprovide complimentary semi-circular portions I3 and |4, which define a passageway l there- These sections 3 and I4 are hinged by a pin i6 o n-a vertical axis for lateral swinging, so that the passageway I5 may be opened to remove the oil saver and stripper from the pump line.` As is shown in Figures 4 and 5 of the drawings, the section I0 of the housing C is provided with lugs 20 and 2| to receive the pintle I6, and the other section is provided with an intermediate lug 22 to receive this pintle. Diametrically opposite, the housing section |0 is provided with a pair of lugs 24 pivotally receiving a lock bolt 25 which is adapted to swing into position between corresponding lugs 2'| provided on the other housing section Il, as shown in Figure 2. rlfhe lock bolt 25 at its screw threaded end .is provided with a lock nut and washer arrangement 28 by means of which the sections |0- and `|l may be -clamped together to assemble the oil saver and stripper housing in position for receiving the casing or casing head. Y

Each housing section I 0 and is provided with a lateral tubular extension having a passageway 3| wherein the wiper D orv Efas the case may be, is rotated, or moved towards or away from the sucker rod passageway l5. The tubular portions are externallyfscrew threaded at their outer ends to rotatably receive caps'or rotary control members 32 with which the means F and G are associated for rotating and longitudinally moving the wipers.

The controlling means F and G for each wiper have cooperatively related parts including a wiper supporting member 40, generally of cup shaped formation including aflat vertically positioned wall 4| upon which the wiper is removably mounted. Furthermore, each cup shaped member 40 -includes an annular wallconstruction 42 arranged on a horizontal axis, provided with diametrically opposed slots 43cut inwardly from the outer edge thereof for` slidalolyA receiving therein tongues 44 of a stub sleeve 45 which is welded or otherwise secured at 46 to the inner surface of the end wall of the housing cap 32, as clearly shown in Figures `3 and 6 of the drawings. These tongues 44` slidably` t `in the slot 43r and thus provide a tongue and slot connection for the wipers D and E upon the caps 32.

The-wall 4| of each wiper supporting member 40 is provided with a key 50 of T-shaped cross section, on the sucker rod facing side thereof, diametrically extending across the face of the wall 4|, as shown in Figure 7 of the drawings. The wipers D and E are each provided with a. corresponding key; Way 5|. The wipers D and E are preferably of rubber or composition with `a rigid crank yor handle 83.

material, suitable for stripping oil from sucker rods, and preferably flexible enough so that they may be placed in abutting relation for properly and completely sealing oiT the well. Generally, the wipers D and E are of cylindrical formation,

Vand each of them is provided with a sucker rod purposes, each cap 32 is provided lwith-a handle 60 by means of which it may be rotated. Since the tongues 44, which are rigid with theseA caps 32, 'are received in'tl'ie 'slots -43 of the' wiper supporting members 4`it is readily apparent that rotation of the caps '32 will also cause rotation of 'the wipers. "The `rotation of leach fcap '32 4is Elimited lto a quarter turn, by means of a screw 6| mounted on 'the housing and received within a`9'0 degree'slot 563 provided in the sleeve v"portion of lthe cap 3K2, as 'shown in Figures -1 and 3 of the drawings. It "is 'thus apparent that, in

'the position shown in Figure 3, thesucker-rod receiving 'grooves j52 can 'be disposed Vin yfacing 'relation lto provide la sucker rod receiving -pas 'sageway By rotatingthe caps it is also apparent that "the wipers 'D "and -E can lbe placed at anan'gle of 90 degrees with respect 'to the sucker rod passageway' |5'|, -'in the `position shown in Figure 5. 'This will close olf "the sucker rod `Vpassageway completely.

'It should be noted that the"p c' rtions i3 rand I4 forming the circular rod receiving 'sleeve of 'the housing lC 'may be lsealed b'y suitable lpack- 'ing means. Thus, *arcuate packing 65 may be embedded :in suitabie grooves fin lme vfacing'nous o'f ythe sleeve portions |'3 and I4, and lclamped in sealing relatio'nbythe bolt means 25 above described, and as can Vbe 'readilylunderstood from 'Figures'L 4, Vand 35. JThe space dividing Ythe 4split line :of the sections |'3 vand I4 is yrather exaggerated in Figures 1 and 2 of the drawings. jAny suitable packing means :may beplaced 4upon the screw threaded *portion lHl o'f the lhousing C where the same receives the v'casing yor casing head, as will be well understood -bythose skilled in the lar'tfto which Athis vinvention relates.

Referring 'to `further details of lthe means 1F for advancing land retracting the `wipersD 'and E, it should fbenoted that *the wall 54| of each wiper supporting member All-'at its 'outer surface is provided with :an axially yeizt'ending feed screw 15 which extends through ian' opening "I6 in vthe outer wall of the cap Y132. In 'this opening 16 there is Ydisposed 'a nut @B ythreaded-'upon the screw 15, and bearing 1in 4the "opening TS. 4vExternally of the c ap 32 'thisfnut 1'il'ii'is provided Rotation of the nut j8|) -by "means 'of the handle'83 'will feed the screw "|'f5 inwardly -or r'oui'.wardly land thus 'feed the -wiperD or E, as Athe case may "be, towards vor faway yfror'n'the lsucker rod jA =re taining -nut 8"6 'may be :placed -upon the feed .screw for holding the nut' in a definite adjustment. A compression spring "9!)fis placed in "each housing sleeve, bearing in lthe `-cup shaped member 40 against the wal-1 idl at one end I:and ,l

"at fits `opposite end enga-ging the outer wall or the cap 32. The function or" the springs 9|) is of course to force the wipers in the direction of the sucker rod B.

In order to limit the outward movement of the nut 8D a lock washer arrangement |00 may be provided on the inner end of the same, as shown in the drawings.

The operation of the improved oil saver and stripper will be apparent from the foregoing. Due to the cooperative relation of the means which enables the wipers to be fed toward or away from each other or rotated through degrees it is possible to regulate these wipers for ecient wiping from the sucker rod, or by simple turn to completely close o the well passageway. The wipers can be completely retracted in the passageway/s 3| in order to permit the-traveling valve to be pulled out without damaging any part of the equipment.

Various changes in the shape, size and arrangement of parts may be made to the Aform of the'invention herein shown and described,

without departing from the spirit of the .invention or the scope of the claims.
